Ophcrack Live CD – Crack Windows passwords in minutes
PaulSpoerry | January 9, 2007
The free, open source Ophcrack Live CD is a Windows account password cracking tool designed to help you recover lost Windows passwords.
After you download the 462mb .iso and burn it to a CD, just restart your computer and boot up the Live CD. Once the CD boots, blamo… Ophcrack automatically loads and is on its way to cracking your password.

Features:
- Runs on Windows, Linux and Mac OS X (intel).
- Cracks LM and NTLM hashes.
- Free tables available for alphanumeric LM hashes.
- Loads hashes from local SAM, remote SAM.
- Loads hashes from encrypted SAM recovered from a Windows partition, Vista included.
I’ve yet to try this live bootable version, but I used l0phtcrack (now LC5 and no longer produced since the company that made it was bought by Symantec) a few years ago and retrieved 99% of the passwords off a backup domain controller in something like 12 hours (using a not-so-powerful desktop to do the cracking).
Get ophcrack Live CD. FYI – you can still get l0phtcrack (aka LC5) from mirrors like sectools.org.
STUMBLEUPON UPDATE:
A couple people have asked if this really works. I just want to re-iterate that this DOES work. It requires physical access to the machine, but if you have physical access you can literally crack every password on a machine in a very short time. As I said above, I used it on a backup domain controller and in about 12 hours cracked every single password on the BDC.
Why crack passwords when you can just create a new Admin account?
Most people tell me they simply “lost” their password. If that’s the case you can use some free tools to create a new Administrator account. With this account you can simply change the existing accounts password, use the new Admin account, or… well… do anything you want. Read more in my article: Hack Vista – Create a new admin account

I would like to introduce Windows Password Recovery Tool 3.0 . it not only supports XP, 2000, and NT, I have personally tested it with Vista Home Premium and Ultimate. It works perfectly to reset any local user account to a blank password. I Wrote it to an old 128mb USB flash drive do this. Booting up and clearing a password takes a minute or two works like a charm. You can download it from http://www.windowspasswordsrecovery. com

Using the Third part utility—Windows Password Unlocker is highly recommended
1.Download Windows Password Unlocker from Password Unlocker Official site
2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker.
3.Insert the newly created CD into the locked computer and re-boot it from the CD drive.
4.After launched the CD, a window pop up with all your account names(if you have several accounts); select one of the accounts that you have forgotten its password to reset it. Just one press, you have removed the password.

A few days ago, I had met the headache things that I had forgotten Windows login password. The login screen rejected my passwords. I was frustrated because there was very important data on my disk and I couldn’t reinstall the OS. …………. However, I fortunately got to know the Windows Password Unlocker, which is a professional windows password recovery tool for us to reset windows 7 password instantly yet no data loss.
You can reset windows user account password in safe mode(F8 when booting up). But if you forgot administrator password, you must reinstall windows OS or use windows password recovery disk. http://www.windowsloginrecovery.com
